Meta Software Developer interview questions

Worst experience with the fb recruiting team! Was really excited about the opportunity but would never ever recommend anyone. My friend referred me to facebook, got an email to schedule a prescreening call. I scheduled it as per the instructions. Recruiter never replied and never called at the scheduled time. I asked my friend to check what's going on! He found out that the recruiter is ill and in hospital, which is understandable (Hope she gets better soon). He mailed her manager about the situation, next day, I got a reject directly without any prescreening call or anything! Things they should learn from Google! Even though they have 5-6 times the number of employees and maybe much more applications, their recruiting process is much smoother!

Phone screen. I have a feeling that hiring process in Facebook is very biased against female candidates, as I did quickly solve both of the exercises in the most efficient manner, but I received the feedback about my coding being "bad" and my solutions not being "brilliant" (it's a quote!). I've got 7 job offers during the last month, 4 of them in the top companies, how could my coding be that bad to not pass a phone screen?
